Thanks for your reply! (Liang and I work together.) The restriction to
"simple" union types is still there in the latest code; see lines 83-95,
I know that elephant-bird has full schema support for reading/writing
protobuf (please correct me if I'm wrong). However, I am unaware of any
alternative to AvroStorage for pig. We may just need to implement it
ourselves, since it is a blocker for using pig with our avro schemas.
Perhaps, someone on this list knows another workaround?
